The mare went first and as she passed through the shield she looked back and spoke, "You're gonna look for the shards right?" She said with a little smug face. "You want to find the elements of harmony and be a hero. Stop looking. They're long gone, they were destroyed along with its tree after the death of Princess Twilight."
Stardust wasn't sure what to say, so she just waited as the rest of the group that was still together got down into her home. She looked around just to make sure no one else was around and then she went below and latched the door. She descended down the stairs and into the main room. She looked to the mare and began to explain herself.
"Yes, I did mean the shards, my years of research and charts have shown me roughly where the shards would likely be. These maps and research has been passed down from generation to generation of astrologists. They have been placed in a new area each time they were passed down and the only ones who could find where it was all hidden were those who knew where to look based on the stars."
She walked over to the other side of the room and showed the group her pile of charts, maps, and research. "I am not going to give up, and who knows, I might be wrong, but if I am right... then that is just one step closer to stop Sombra. I don't want to be a hero, I just want to help all of these ponies that have given up hope. My father never gave up hope and he fought, and that is why he is gone. My mother... she gave up hope... and I saw her transform into somepony I don't know. That is why I am searching so profusely... to save hope."
She moved into another room and came back with a basket full of food and a water pitcher. "Here, please eat and drink. Rest, get your strength back. We must get your magic back before you try and leave for the Griffon Island. I have a friend that can make it happen. No one will be able to come in or out once I leave, don't go up the stairs after I leave for anything. If your friends come looking for you they will not be able to reach you. I shouldn't be long, I will bring my friend so she can get a good look at you and we can discuss how we will move forward."
Stardust turned and walked towards the stairs, "I promise I will be back." And with that she was gone.
